To 1/Z whom t may concern:

Be it known vthat I, AUGUST HEINRIC WIL- HELM WEDLER, umbrella manufacturer, a subv ject of the King of Great Britain and Ireland,

and a residentiof 141 Bundle street, Adelaide,

vin the vState.of.,South Australia, Commonwealth of Australia, havefinvented acertain new and useful Improvement in Devices for Fastening, Adjusting, and Locking Window- Sashes, of .which the following is a specilication.' L.

Thisfinvention is devised to afford a sash fastener andadjuster in combination .for the purposes of fastening' and .securely locking the sashes of windows whenv closed .andfalso when adjusted with' an opening. at top or bottom or atbothtop and bottom.A f

Anessential feature of my inyention isv the described Iconstruction of the .piston-head and the combination therewith of the springand cam, whereby. theautomatic fastening action is attained. The main portion of the appliance is cast in brass or other approved metal. The piston-head is constituted of hardened steel inthe shape described and illustrated.

In order thatthe inventionmay .be clearly understood, I will describe the same with referenceto'the drawings.

Figure lis a plan of my sash'fastener and adjusterwith extension-bar in horizontalpoisition. Fig.` 2 is a front View ofupper sash portion only ywith extension-bar in horizontal position. Fig. 3 is a frontview of upper sash portion'only with extension-bar in Verticalposition. Fig. 4 is a vertical .sectionwithextension'- bar in vertical ,position and safetylock'engaged.. The key for the safety-lock lock. In:Fig..8.the piston serial No. 168,630. (No model.)

of, and.' the other part. is fitted and secured upon the lower bar of the upper sash in a corresponding position. vThe portion upon the llower sash` comprises a barrel A, having a suitable bed whereby it is screwedv or `other. wise fastened to the sash, a piston B, adapted to be moved to and fro in the barrel by means of 'a cam or quarter-eccentric C. and-a spiral spring E, respectively, and a lock VF for preventing the withdrawal of the piston. The-bar.- relA has its front end quite open, but at its rear end is ashoulder to retain the spiral spring E. The piston B has a slotted stem B', encircled by the'spiral spring E, while its head is of two diameters, one portion fitting neatly within the barrel lAy andthe other portion being of reduced diameter, the shoulder beingnot square, but neatly rounded out, as shown. The piston may be of'steel or other metal or partly of one and partly another, provided the head is of hardened steel and of the shape described. The cam or quarter-eccentric Oissecured upon a pivot-pin D within a slot in the stem B of the piston,l andv its cam-face operates within a vertical slot in the rear of the barrel The' cam-face has an indent O2, which engages the vbarrel end when the piston is withdrawn. The spiral spring E encircles the stem Bv fof the piston andis confined between the'head of the piston Aand the back of the barrel, so that it tendsto project the piston forward.-

The normal position of theV piston and cam is as shown in Fig. 7 In order -to withdraw -the piston B, it is only necessary tov raise the thumb-piece O of the cam untiltheindent C2 engages the end of the barrelgas shown in Fig. 8. Asthe cam-face slides upon 'the'end of the slot. in the barrel the body of the cam and 4the piston B are forced back against the springE. The cam will remain in this position untilthis thumb-piece is depressed.

The lock, which is not shown in Figs."7 and 8, consists of a bolt F, having a screw upon its central portion, an enlarged footionits lower end, and a stem atits upper end suitably shaped to take a key K. (Shown only in Fig. 4:.) This bolt is carried in ashort perpendicular tubular portion A', extending upward from the barrel A. The lock-bolt F when in use is screwed down by means of the key K until the foot engages ashoulder'or bed in the piston-head, as shown in Fig. 4. When the lock-bolt F is not in use, its position is as shown in Fig. 6. The cap H (shown in Fig. 4) is placed over the head of the stud F when the key K is removed to prevent the entrance of dirt.

The portion of my appliance upon the upper sash consists of a receiver-body L, Ahaving a suitable bed, whereby it is screwed or otherwise fastened to the sash, an extension-arm M, pivoted to the receiver, a retaining-spring N for holding the extension-arm when in its vertical position, and a hinge-pin P, upon which the extension-arm M is pivoted and which holds the spring N in position and which has a central opening to take the piston-head B when the window is closed.

The extension-arm M has a beveled projecting portion l which is vertical when the extension-arm is horizontal, as shown in Figs. l and 2, and serves as an automatic guide to the piston B. When the arm is in this position, the action of the fastener is exactly the same as with the construction shown in Figs. 5 and 6, the window being fastened automatically either from inside or from outside, but in the closed position only. The hole in the receiver-body, sometimes called the fixed receiver-hole, inthe cases where the adjusting-arm is used is formed in the center of'the hinge-pin P and in other forms is drilled in the fixed bed itself.

When it is desired to fasten the window with an opening at the top or bottom or at both top and bottom, the extension-arm M is raised to the'position shown in Figs. 3 and 4. The arm is held in raised position first by means of the spring N, the point of which enters a recess in the rear of the arm, as shown in Fig. 4, and secondly by the projection i coming into contact with the bed of the receiver L, as shown in Fig. 3. The piston is withdrawn from the receiver-hole, and if the lower sash is now raised the piston B can be made to enter any one of the holes M2 in the arm M. The same action is obtained by lowering the upper sash the desired distance. The two sashes are then held fastened to each other in the desired relative position.

The parts illustrated in Figs. 7 and 8 upon the lower sash with the parts illustrated in Figs. 5 and 6 for the upper sash exhibit the most simple form of my sash-fastener without the safety-lock or opening-adjuster, but containing the essential feature of automatic closing action by means of the piston-spring and cam.

Owing to the shape and the material of which the piston-head is constructed, it is impossible for the window to be burglariously opened by the sawing of the piston-head between the sashes.

The use of the key-lock enables the window to be fastened by the owner or occupier and so locked that it cannot be opened either from outside or inside without the production of the key, an additional safety to householders.

Having now particularly described and ascertained the nature of my said invention and in what manner` the same is to be performed, I declare that what I claim isl. A sash-fastening device comprising in combination the following parts secured to the lower sash, namely, a barrel, a piston of' the construction shown, a quarter-eccentric campiece pivotally attached to the said piston, a coil-spring acting to project the said piston, a key-lock upon the said barrel, a key fitting into such lock, and the following parts secured upon the upper sash, a receiver-bed, an extension-arm adapted to lie horizontally or to be raised erect, a spring for retaining the said arm in its erect position, and ahinge-pin which carries the said extension-arm and the said spring and is bored with a fixed receiver-hole, the said arm having a series of receiver-holes in a vertical line with the fixed receiver-hole and with the piston when said arm is erect, and having also a beveled receiver-lip adapted when the arm is in horizontal position to allow thepiston to automatically slide into the fixed receiver-hole, substantially as described.
